[StimulusBundle] Document chaining different stimulus_* helpers

[Amoifr]

Q	A
Bug fix?	no
New feature?	no
Docs?	yes
Issues	Fix #3794
License	MIT

The docs already show chaining the stimulus_controller, stimulus_action and stimulus_target filters with themselves, but not that they can be mixed freely to build all the attributes of an element in one chain, as suggested in #3794. This adds a short section with the example (rendered output verified against the actual helpers) and a unit test covering mixed chaining, which no test exercised before.

Again, please target the branch 3.x...

[Amoifr]

Done, rebased and retargeted to 3.x — and noted for good this time: 3.x it is for everything ux. Sorry for the repeated 2.x reflex! Suite green on 3.x (21 tests).
